VEHICLE-HUB.

SPECIFICATION forming part of Letters Patent No. 381,891, dated April 24, 1888.

Application filed January 3, 1888.

To all wwm it may concern:

Be it known that I, MOSES E. TRUE, a citizen of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented a new and useful Improvement in Vehicle-Hubs, of which the following is a specification.

My invention relates to improvements in vehicle-hubs in which a metallic shell band having spoke-sockets is made to register with corresponding sockets formed in a wood hub and about which the metal portion is centrally placed; and the objects of the-improvements are, iirst, to provide a band made from a single piece of metal capable of being driven over this wood portion of the hub, so as to compress the same in such manner that the two parts will be interlocked one with the other, and, second, to afford means of interlocking the spoke with the metallic band to prevent lateral displacement. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a sectional view taken through the longitudinalA center ofthe hub with the band in position. Fig. 2 is a perspective crosssectional view of the hub with band and spokes in working position, and Fig. 3 is a cross-sectional view of the band detached.

Similarletters refer to similar parts throughout the several views. The hub A is made from a single piece of wood, as herein shown; but the same may be made in parts, ifdesired.

B is the metal band, having spokesockets b, of suitable dimensions, for receiving the full size of the spoke C, which spoke also enters the hub in its full dimension for a portion of its depth,(as at 0,) while the usual tenon is used upon the inner end of the spoke.

The band B is made tapering upon its inner circumference, being of less diameter' at one end (as at b) than it is at the other, while the outer circumference is the same for the greater portion of its length, the front end being rounded to an edge and upon the outside,while the rear end is inwardly beveled, (as at 112,) for a purpose now explained. It will be seen that the hub A is made diametrically smaller at b than it is at the front end of the band and of Serial No. 259,700. (No model.)

shape corresponding with the inner surface of the band. Now, as this band is driven upon the hub from the front or enlarged end this enlarged portion must be compressed, which is done while in the act of driving the band by means of the inwardly-beveled end,which rst comes in contact with the enlarged portion of the hub, therebycompressing the same, the hub assuming its normal position after the band is seated in its place, thus interlocking the wood and metal and preventing lateral displacement.

Referring now to the spoke and the manner oflocking the same with the hub, it will be seen that the spoke enters the wood hub at its full size for a portion of its depth, and is provided with notches c upon either side, the notches being in the shape of `a half dovetail having asquare shoulder,which shoulder, after being driven, is Hush with the circumferential part of the wood hub and immediately beneath the innercircumference of the band, and as the part of the spoke below these notches `is laterally compressed in the act of being driven it will again expand to the normal-position after passing the metal, so that these square shoulders reach underneath the metal bars upon either side, forming a square lock therewith. 'Ihe metal band is provided with cross-bars B', which form the partingwall be tween each spoke; also, the side wall of the spoke-mortise. These walls are made dove= tailing in cross-section, being wider upon the inside of the band than upon the outer side thereof, so that the hub-mortise at its peripheral part is of a size corresponding with the base of the spoke.

Now it will be observed that when the mortises have been made in the hub and the band driven thereupon the inner edge of the beveled parting will project over the edge of the mortise, so that the spoke, after being driven,will by the notches in the same become interlocked underneath the bar, thus preventing the spoke from being withdrawn wit-hout breaking either the bar or spoke, In driving the spoke the part below the notch is gradually compressed in its passage through the metal until the notch passes the bar, when the compression is released, thereby permitting the spoke to assuine its normal position, so as to fill the 1nor tise in the hub, all of which Will be understood without further description.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The Wooden hub having a band-seat diametrically smaller at its rear part, in combination with the metallic band,made thicker at one end so as to form an inward taper corresponding with the seat upon the hub,and provided with a month flaring outwardly from the contracted part, so that in driving the band the mouth Will rst encircle the enlarged part ofthe hub,co1npressing the same while in the act of being placed thereupon, and afterward allow ofthe expansion of the same to its nornial position, thereby rmly interlocking the parts, substantially as described and herein set forth.

2. The combination ofthe Wooden hub having the peripherallyenlarged mortise for the reception of the fullfsized spoke a portion of the depth, the smaller mortise for the recon tion of the spoketenon, the metallic shell hand surrounding the hub, having theinwardly-heveled spoke-parting walls, the bevel of which extends in a straightline the entire thick ness of the band, and the spoke having beveled MOSES E.
